Here's the Western Veil Nebula (really a supernova remnant) aka the aptly named Witch's Broom (NGC 6960) as taken from our driveway in Northern Virginia.

This image is a new PR for me with over 10 hours of exposure time captured over four nights. This object features beautiful layers of filaments of hot glowing hydrogen (red) and doubly ionized oxygen (blue/green) gas seen almost edge-on as it expands through space from the supernova which occurred (or was seen on earth) approximately 5,000 years ago. This object can be found in the northern hemisphere in the constellation Cygnus (The Swan). Image specs:
Ha 45x400", 30 dark frames, 40 flats, 40 dark flats.(5hrs)
Oiii 23x900", 30 dark frames, 40 flats, 40 dark flats.(5.5hrs)
Camera cooled to -6c, 1x1 bin, unity gain settings (120). Astrotech AT111 Triplet Refractor, Zwo ASI294MCPro camera, Zwo Nb filters, Skywatcher EQ6-R Mount, Orion .80x reducer. Captured in APT, DSS, Startools, and finished in Lightroom CC.
